A hardware-based Dvorak Simplified layout. At my weekend job, I use a shared computer that runs MacOS Sierra, in US QWERTY layout. In this layer, I can leave the system in QWERTY, plug my keyboard in, and still type in Dvorak.

These layers were born out of the confusion I have had trying to use the in-game chat and the console in [Quake 2](https://en.wikipedia.org/wiki/Quake_II). When Quake 2 came out, alternate keyboard layouts weren't really a thing. As a result, all in-game text input is hard-locked to US QWERTY, regardless of what the operating system is using for its input method.
I have solved this by writing a custom QMK macro. The keycode in the System layer that enables these layers, [`GO_Q2`](./keymap.c#L205), is a [macro](./keymap.c#L63-L70) that sets the default layer to the QWERTY layer, then turns the Quake 2 layer `_Q2` on. The result is a partially-overwritten QWERTY layer, that changes the dual-function Left Control/Grave key to a standard Left Control, and the Enter key into a special Enter key specific to Quake 2.
When I hit the `Enter` key (bound in-game to text chat), the [macro keycode](./keymap.c#L71-L86) I've created sends the keycode for `Enter`, then follows with flipping an internal boolean variable and enabling the Hardware Dvorak layer. Now the game is in text chat mode, and my keyboard is in Dvorak. When I hit `Enter` again, another `Enter` key is sent, which sends the message, then the macro flips the boolean back to false and disables the Hardware Dvorak layer, which brings me back to the standard QWERTY+Quake 2 setup. Hitting `Escape` instead runs a [macro](./keymap.c#L87-L97) that cancels the sending of the message, and undoes the layers.
- Accessed by holding either `Fn` key from any base layer
Arrows, Navigation keys (Insert, Home, Page Up, etc.), and Function keys are here. Also has keys for Calculator, Menu, Volume Control, and shortcuts for Select All, Undo, Cut, Copy, and Paste. Numpad Enter for when I'm working in Adobe Photoshop, because it treats Numpad Enter differently from the regular Enter key.
- Accessed by holding either `Fn` key and tapping the `/?` key
This is where I change my keyboard function. Base layer select on `1` through `4`, Backlight controls on `C` through `N`, Reset on `8*`, Debug on `0)`. Hitting `Esc` exits the layer.
